Are there any weapons where I can get all/some/most of the talents unlocked when used in combination with the tactician's set ?
I am playing a support/healer build
my Tactician's gear statsso far
Tactician's vest +464 stamina
Tactician's mask +603 stamina
Tactician's knee pads +541 electronics
Tactician's pack +665 electronics
Tactician's holster +537 firearms +467 stamina +489 electronics
(NO GLOVES YET)
At the moment....Electronics aren't really good for PVP'in but they help with skill cooldowns....so I would go with an AR or SMG with skill cooldown reductions. Since you have low fire arm skills I would focus on finding an SMG that has good crit chance. Focus your sets on crit chance so that you can do damage when your skills are on Cool Down. Black Market AK or the AUG are good weapons to get the rolls on.
Also try mod slotting some firearms into those gear pieces. I would also try to use two Sentry pieces that give you head shot damage. I wouldnt worry about getting the full set...where you only need 4 to get the perk. If they had a full set build it would be good to do it. I would use the other two slots to play around with and help you get more Firearms builds
